Hey, here´s an Ensoniq EPS-16 Plus Emulator

Well you are right some effects load and work ok. Rez and FM are consistently not working (tried multiple files I downloaded from the net).

I tried to get some help from chat gpt but no solution

(what it said was)

  • some effect opcodes haven’t been implemented,
  • some DSP microcode formats aren’t supported yet,
  • or the loader is stricter than the original hardware.

The weird thing Is that just before “Effect download failed” comes up the message on the screen for just a few miliseconds is “Disk command completed”

I‘m on it! :slight_smile:

Thanks alot! I will move on to the fx-disks later.

Is there any ready made floppys out there with samples on it? some factory disks with presets or anything? :grinning:

Sure, google will help you, just make sure it’s an hfe file so the Emulator can load it.

I can’t find anything really besides some link to eBay or some random blog selling the files for 30$-50$ each.
I might be the worst googler lol

anyway I can create my own sample disks instead I think its a better idea.
Really great job and Im learning it at the moment. :slight_smile:

You´re really not missing on out on great sounds, it was bread and butter sounds only of which you can get much better variants today easily. in my opinion the EPS´s strengths are is the sound with the various samplerates, its looping loopmanipulation and modulation capabilites. Try to understand the envelopes, they´re very complex but really great. basically you can set different levels for low and high velocity, the actual playing envelope will be interpolated between those two curves based on the actual velocity you´re playing. oh, also use boost=on on every sound (edit->amp), it sounds great.

It’s pretty Menu-heavy but Im learning to sample atm… taking one step at the time. If I can create a Drum kit and save it, then that’s my gran goal for the weekend.
I need to think like im sitting in front of the thing!
I have no idea how the original is but what I can tell from your plugin is that it operates exactly like I imagine an early 90’s sampler would. I would also love to try out that demolition disk, Rez filter and yeah create sounds. Man this is so dope!

I really wish it had a piano-roll attached so I could click on the keys to localize where the sample actually is. More easy to memorize I think, Specially when having many different sounds for example.

Not a big deal for sure cus I can put triggers in Live but that piano-roll is kinda crappy really.

I could do that, noted!

1.0.3 now available for download.

  • Added an expandable 61-key on-screen keyboard with click-height velocity, delivered through the original EPS keyboard-controller path.
  • Added hardware-style Pitch and Mod wheels. Pitch returns to centre, Mod remains latched, and both use the original analog controller inputs.
  • Added Intel x86_64 support targeting macOS 10.13 High Sierra. The universal VST3 contains both Intel and Apple Silicon code in one installation.

1.0.7. available now

1.0.7

  • Added the original EPS-16 Plus Level Detect meter. The VST renders the bar count and independent Trigger Sensitivity marker sent by the Ensoniq OS/KPC; it does not calculate a separate host-side level.
  • Fixed live volume-value updates on the LOAD/Instrument page by decoding the original OS direct-cell VFD writes; the page remains cursorless exactly as transmitted by the Ensoniq OS.
  • Fixed live instrument-name editing so cursor movement and replacement characters follow the original OS VFD command stream instead of repeatedly redrawing the first letter.
  • Increased display polling to 30 Hz for responsive metering while keeping ROM/resource discovery and status work on a slower cadence.
  • Reduced plug-in CPU overhead by publishing display state once per DAW audio block and excluding probe-only 68000 diagnostics from release builds.
  • Renamed the public plug-in and package from “EPS-16 Plus Prototype” to “Ensoniq EPS-16 Plus”. The VST3 identity remains unchanged so existing DAW projects and presets remain compatible.

Wow you are on fire!
Cpu was an issue alright, also cursor on editing is a big qol improvement.

This has become my fav synth since I downloaded it. You have made the dream of beeing able to play the EPS true! I have no words, I truly thank you for making this and keep improving it!

I should probably upload some sounds of the patches I have made so far, it really sounds fantastic and so unique! :pray: :pray: :pray:

I used to own an eps16+ rack… my first sampler…

sorry to be that guy but i can only find images with names that have Upper and Lower.
I am curious if the files it asks for in the Readme are the only EPS16+ bin files it will take (combined into one)

I had a much easier time finding all the files for the SD-1 plugin :wink:

I got it working

for those who might be confused like i was

  1. the newest version can take the upper and lower but you have to rename the files to .bin
  2. I had trouble because I did not have the proper dir structure
    even though I am using the AU once I put the files into VST3/EPS_Files it all worked

THANKS SO MUCH FOR THIS AMAZING PLUGIN
